Abstract
UN CATALIZADOR DE PIROLISIS DE HIDROCARBURO CON DEPOSITOS DE COQUE, SE REGENERA MEDIANTE LA COMBUSTION DE LOS DEPOSITOS EN UN REGENERADOR (2) CON UNA ZONA DE COMBUSTION INFERIOR (12) Y UNA ZONA REDUCTORA SUPERIOR (14). UNA MEZCLA DE OXIGENO Y UN GAS INERTE (POR EJEMPLO NITROGENO O DIOXIDO DE CARBONO) SE INTRODUCE EN LA ZONA DE COMBUSTION (12) A TRAVES DE UN DISTRIBUIDOR. LA ZONA DE COMBUSTION (12) TIENE AL MENOS UN 24% DE VOLUMEN DEL INDICE DE FLUJO TOTAL DE TODOS LOS GASES EN LA ZONA (12). SE COMBUSTIONA AL MENOS PARTE DEL COQUE. ADEMAS, EL NITROGENO EN EL COQUE SE CONVIERTE A OXIDOS DE NITROGENO (NO{SUB,X}). UN GAS DE COMBUSTION SUSTANCIALMENTE SIN OXIGENO, INCLUYE UN DIOXIDO DE CARBONO, OXIDOS DE NITROGENO Y AL MENOS UN 1% DE VOLUMEN DE MONOXIDO DE CARBONO, QUE FLUYE EN LA ZONA REDUCTORA (14) CON EL RESULTADO DE AL MENOS PARTE DE LOS OXIDOS DE NITROGENO REDUCIDOS A NITROGENO.A HYDROCARBON PIROLISIS CATALYST WITH COKE DEPOSITS WILL BE REGENATED BY COMBUSTION OF THE DEPOSITS IN A REGENERATOR (2) WITH A BOTTOM OF COMBUSTION AREA (12) AND A SUPERIOR REDUCING ZONE (14). A MIXTURE OF OXYGEN AND AN INERT GAS (FOR EXAMPLE NITROGEN OR CARBON DIOXIDE) IS INTRODUCED IN THE COMBUSTION AREA (12) THROUGH A DISTRIBUTOR. THE COMBUSTION AREA (12) HAS AT LEAST 24% VOLUME OF THE TOTAL FLOW RATE OF ALL GASES IN THE AREA (12). IT COMBUSTS AT LEAST PART OF THE COKE. IN ADDITION, THE NITROGEN IN THE COKE IS CONVERTED TO NITROGEN OXIDES (NO {SUB, X}). A COMBUSTION GAS SUBSTANTIELY WITHOUT OXYGEN, INCLUDES A CARBON DIOXIDE, NITROGEN OXIDES AND AT LEAST 1% OF CARBON MONOXIDE VOLUME, THAT FLOWS IN THE REDUCING ZONE (14) WITH THE RESULT OF AT LEAST ONE OR LESS THAN NITROGEN REDUCED TO NITROGEN.
